目的 为飞机整体油箱内的微生物影响下各材料的性能变化以及环境适应性设计改进提供理论依据和实验支撑。方法 以2A12、7B04铝合金和HM系列密封胶为研究对象,使用SEM、XRD、FTIR等技术,采用浸泡试验,从电化学、腐蚀形貌等角度进行试验验证,对比分析多周期下有菌和无菌对材料的性能的影响。结果 希瓦氏菌明显促进了2A12和7B04铝合金的点蚀,且7B04的腐蚀程度和电化学活性更为明显;硫酸盐还原菌对HM112等的密封胶也有劣化作用,在出现不同程度的孔洞的同时,官能团组成也发生了变化。整体油箱的常用材料在微生物,特别是细菌的影响下,其组分和腐蚀性能均受到不同程度影响。结论 飞机整体油箱作为现代飞机常见的油箱结构形式,其材料的环境适应性设计不仅要考虑到外部环境,也应顾及内部环境即在微生物污染下的燃油介质,特别是细菌的影响,这为飞机整体油箱材料的环境试验验证方面提供了一种新思路。
Abstract
The work aims to provide a theoretical basis and experimental support for understanding the performance changes of various materials under microbial influences within aircraft fuel tanks and for designing improvements to enhance environmental adaptability. 2A12 and 7B04 aluminum alloys and HM series sealants were selected as research subjects. Techniques such as SEM, XRD, and FTIR were employed, and immersion tests were conducted to experimentally validate the effects from electrochemical and corrosion morphology perspectives. The impacts of microbial presence versus absence on material performance were compared and analyzed under multi-cycle conditions. Shewanella Indica significantly promoted pitting corrosion in both 2A12 and 7B04 aluminum alloys, with 7B04 exhibiting more pronounced corrosion severity and electrochemical activity. Sulfate-reducing bacteria also degraded HM112 and other sealants, resulting in varying degrees of porosity and changes in functional group composition. Common materials used in integrated fuel tanks were subject to varying degrees of influences on their composition and corrosion performance under microbial, particularly bacterial, conditions. As a common fuel tank structure in modern aircraft, the environmental adaptability design of aircraft fuel tank materials should consider not only external environmental factors but also internal environmental factors, specifically the impact of microbial contamination on fuel media, particularly bacterial influence. This provides a new approach for environmental testing and validation of aircraft fuel tank materials.
